Path optimization method based on complex sea conditions

The invention discloses a path optimization method based on complex sea conditions, which is mainly applied to an offshore unmanned autonomous intelligent search and rescue platform, and comprises the following specific steps: when receiving a rescue signal, firstly dispatching a search and rescue platform carrying offshore monitoring equipment to the vicinity of the signal, and transmitting the sea conditions to a command center by utilizing the offshore monitoring equipment; the command center generates a sea condition distribution diagram according to the information, makes concentric circles according to the actual situation, determines the number K of levels of the search and rescue area, generates the distance between each level and each point of the next level by using a computer, generates a sea condition distribution diagram with distance marks, and iteratively calculates the shortest distance by using the idea of dynamic planning iteration, so that the search and rescue area is obtained.
